Sadly, unscrupulous collectors have decimated many wild populations of Trillium and many are now endangered. Rest assured that we offer only commercial nursery propagated plants. You can help ensure their survival by planting some in your own garden. You will need to have the appropriate conditions. Trillium are not a good choice for the desert southwest due to its drought conditions unless special arrangements have been made. They are a sight to behold not only in their native habitat but also in the garden. They are recognized by their three leaves and showy flowers. Nearly all parts of the plant come in threes.

Growing Instructions

Plant Trillium outdoors in spring after all danger of frost has passed in a partially shaded to full shade location. The ideal soil is rich and porous and drains well, yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments like peat moss or ground bark. Spread a 3-4 inch layer of soil amendment if needed and incorporate into the soil to a depth of 10 inches. Plant roots 1-2" deep and 12-24" apart. Cover with soil. Water thoroughly at planting. While actively growing, water frequently and thoroughly so that water will reach roots. Mulch to keep the soil cool and to prevent the soil from drying out. Fertilize during growing period.

Care Tip

Trilliums demand rich, slightly acidic, woodsy soil that never dries out so some care is required in choosing a site. In order for Trillium to thrive in the home garden, one must mimic their native habitat by providing moist, well draining soil enriched with organic matter. Once established, they require little maintenance or care.
